How to verify safe stack usage on KL17?

We are about mid point in our development and would like to test if our stack usage is safe (not close to overflowing) on our KL17 processor? What tools are available to a developer to make this assessment? We are using the IAR Workbench IDE.

I think we have not the tools to check if the stack is safe. But I think you can write the stack with a pattern, then running the code and check if pattern has been changed for the out of range of stack memory.
